[Boost-users] [BGL] Mixing bundled properties and property lists

Hi, consider the following (excerpt from a) class wrapper around an adjacency_list: using namespace boost; template <typename VertexProperty = no_property> class MyGraphWrapper { private: typedef adjacency_list > GraphImpl; // ... }; I want to store some property (in this case, a vertex index) inside the graph implementation, but at the same time I want to allow the client to specify further properties via the template parameter. May the client use the bundled property mechanism, e.g. struct Label { std::string lab; }; MyGraphWrapper<Label> g; My test compiled and it seems to run fine. Is it really possible/safe to mix bundle properties with property lists in this way? Or, is there a way to avoid property lists? Nicola
